I have drawn one, and I feel as though I understand how it works, but for me, I feel like the equations get me confused. I am only a sophomore in High School, and this is all very new to me.

I honestly don't understand how it works

Would the equation be a=v^2/r?

A=f/m, so 40.1/1.4? Then that would be 28.6m/s^2 Would I use the equation a=mv^2/r? If yes then it would be 28.6=1.4v^2/1.9, v=6.23, but I was told the answer should be 6.93

Thank you guys! I finally understand how to get the force of tension, but for velocity I am not sure which equation to use.

Great! Please help me with my post in https://www.physicsforums.com/threads/circular-motion-and-gravitation.787037/

Hi! I'm new, a sophomore in AP Physics 1! I'm having a lot of trouble!

Homework Statement There is a tether ball swinging around in a uniform circle on a rope that is 1.90m long. Marcus hit the ball so hard that the string holding the ball made a 20.0 degree angle to the horizontal. What is the tension in the rope if the ball has a mass of 1.40 kg? Assume that the...
